2 Claims.

The present invention relates to a stairway and the object of theinvention resides in the provision of a sturdy structure which issimple, extremely easy and quick to assemble and disassemble, thoroughlyefiicient and reliable in use and otherwise well adapted to the purposefor which it is designed.

With the above and numerous other objects in view as will appear as thedescription proceeds, the, invention consists in certain novel featuresof construction, and in the combination and arrangement of parts as willhereinafter be more fully described and claimed.

In the drawings:

Fig. 1 is a side elevation of a stairway embodying the features of myinvention,

Fig. 2 is a top plan view thereof,

Fig. 3 is a detail elevation showing one of the tread plates in a slotprovided in one of the stringers,

Fig. 4 is a detail sectional view taken substantially on line 4-4 ofFig. 2,

Fig. 5 is a detail side elevation of one of the stringers, and

Fig. 6 is a perspective view of one of the struts.

Referring to the drawings in detail, it will be seen that the numerals 5denote a pair of stringers adapted to be situated on an incline and torest on a mud sill 6 and to be fastened thereto by means of screws 1.These stringers have slots 8 formed therein extending rearwardly fromthe front edges thereof horizontally and these slots receive the treads9 and are secured in place by screws ID as shown to advantage in Fig. 4.The top tread H is secured on the upper ends of the stringers by screwsl2. A pair of struts comprise elongated bodies l4 secured under thelower or rear edges of the stringers by means of screws I 5. The upperends of these bodies 14 merge into upwardly directed extensions l6 whichmerge into rearwardly extending bolts l1. These bolts I! extend througha. beam [8 and a plate l9 and have nuts 20 threaded thereon for securingthe stairway assembly to the upper struts.

It is thought that the construction, manner of assembly and disassemblyand the utility of this invention will now be quite apparent to allskilled in the art without a more detailed description thereof.

The present embodiment of the invention has been described inconsiderable detail merely for the purposes of exemplification since inactual practice, it attains the features of advantage enumerated asdesirable in the statement of the invention and the above description.

It will be apparent that changes in the details of construction, and inthe combination and arrangement of parts may be resorted to withoutdeparting from the spirit or scope of the invention as hereinafterclaimed or sacrificing any of its advantages.

Having thus described claim as new is:-

l. A stairway of the class described comprlsing a pair of stringershaving slots, treads having end portions in the slots, an upper tread onthe upper edges of the stringers, struts having bodies secured under therear or bottom edges of the stringers and at their upper ends merginginto upwardly disposed extensions which in turn merge into rearwardlydirected bolts adapted to extend through openings in a beam or the like.

2. A stairway of the class described comprising a pair of stringershaving slots, treads having end portions in the slots, an upper tread onthe upper edges of the stringers, struts having bodies secured under therear or bottom edges of the stringers and at their upper ends merginginto upwardly disposed extensions which in turn merge into rearwardlydirected bolts adapted to extend through openings in a beam or the like,and a mud sill secured on the bottom ends of the stringers.
